Arsenal boss Arsene Wenger admits he cocked-up at the start of their 2-2 draw with Manchester United on Saturday.

Wenger confessed that Sir Alex Ferguson outwitted him tactically and that he should have played another forward alongside Emmanuel Adebayor rather than leave the Togo striker up front on his own.

Wenger said: "Sometimes Adebayor was a bit too isolated up there. Maybe I could have played Theo Walcott up front, or Eduardo or Niklas Bendtner. But I went for a different approach.

"Without Robin van Persie the balance in the final third was not completely right.

"That's my fault. I'd look at that again.

"In the final third, we dropped a little bit too much off and that took something out of our game.

"The game didn't reach the level in terms of technique that I'd expected it to reach, but it was still an interesting game with contrasting styles."
